Alan Alda (far right) stars in QED with Kellie Overbey at Lincoln Center's Vivian Beaumont on Contact's off nights. At far left is Richard Parnell, who wrote QED and Gordon Davidson, who directed the play.
QED was once called Tuva or Bust! and is based on the book that goes by the latter title, written by Feynman and Ralph Leighton. It traces the two men's friendship from the first discovery of a mutual passion for drumming to Feynman's many wild tales of safe cracking at Los Alamos, sharing gambling tips with Nick the Greek, joking with Einstein and finding the frozen "O Rings," the cause of the Challenger disaster.
